Chrome has been slowly been updating the features of their Global Media Control and in their latest tweak is adding support for Live Captions to the media hub.
Live Caption is a useful feature which uses an on-device AI engine to transcribe the spoken words in a video into text which can be used for accessibility purposes.
The feature is already available on select Android devices and can be activated on the desktop with the chrome://flags/#enable-accessibility-live-captions flag.
Next, when you enable the new Global Media Control at chrome://flags/#global-media-controls-modern-ui, you will have the option of activating Live Captions.
The feature will now enable captions on a wide variety of media which previously did not support it.
The feature should be available in Chrome on all channels.
